OK. What type of test equipment do you have? Also do you have a solid security light in dash when it wont start?

Expert:  Tool Hut replied 9 months ago.

Does the starter crank the engine and it just wont go? Or is it a click or no sound?

Customer: replied 9 months ago.
I don't have any testing sound. And no on the light
Expert:  Tool Hut replied 9 months ago.

without any test equipment it is a shot in the dark and thats not how I work. I will opt out.

Hello and welcome to JustAnswer!

It's going to take some electrical testing to determine what is causing the problem.

If you hear no noise from the engine compartment then odds are the starter is not being commanded to engage which could be the ignition switch, wiring, the body controller, transmission range sensor, the engine controller may not be awake due to an internal failure or a loss of power or ground.

Does the fuel pump run when the key is first turned on at the time it doesn't crank?

Customer: replied 9 months ago.
Just never mind cancel my payment. I just wanted some suggestions of what it my be! Don't contact me pls.
